To all whom t may concern:

Be it known that we, CLAYTON CROUGH and GEORGE J. HEWLETr, citizens `of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio,

have invented certain new and useful Im- .provements in Carton Pasting and Sealing Machines, of which the following is a specication.

Our invention relates to improvements in carton pasting and sealing machines, the improved machine being particularly designed and adapted for receiving the ordinary or conventional form of carton or paper box provided with suitable aps or folds in proper position to be immediately filled with the contents to be'packed vafter which a suitable conveyer is adapted to carry or transport the filled box or carton and deposit a suitable supply of paste or glue over the flaps or folds after which such flaps or folds provided with a suitable supply of properly-distributed paste are automatically folded or closed over the contents of the carton or box and held in such closed or sealed position between suitable carton receiving and sealing aprons for such a length of time as will be necessary for the paste to thoroughly set or dry so that the iiaps will remain securely sealed for the transportation 0r storage of the carton and its contents.

The primary object of the invention is to provide a generally improved machine of this class of exceedingly simple, cheap, and ecient construction for the purposes above mentioned, an'din carrying out this invention the machine is provided at its frontor receiving end with a suitable carton re- 40 ceiving and supporting table where the box. is first set up and filledafter which it is transported by means of a suitablecarton conveyer passing along or between suitable paste applying and carton flap operating devices said flap operating devices being adapted to fold over the freshly pasted iiaps v upon the contents of thebox after which the carton conveyer feeds the completely. folded carton to and between suitable carton receiving and sealing apronsarranged in series and spaced apart to form a suitable carton receiving and transporting guideway through which the cartons are transported through the medium of a second but preferably more slowly moving carton conveyer one member ofwhich moves through the carton receiving and transporting guideway, said carton receiving and sealing aprons preferably passin over and inclosing a series of presser rol ersvadapted to cooperate 'with the carton receiving and sealing aprons in holdin and sealing the carton flaps until the paste 1s thoroughly set so that when the cartons emerge from the delivery end of the machine they are securely sealed for further transportation and storage.

With the above mentioned and other ends in view, the invention consists in the novel construction, arrangement, and combination of parts, hereinafter described, illustrated in one of its embodiments in the accompanying drawings, and particularly pointed out in the appended claims,

Referring to the drawings forming a part of this specification, Figure 1, is a perspec- 7.' tive view of an ordinary or conventional form of paper carton or box as it appears in its initial position and before being placed on the carton receiving and supporting table of the machine preparatory to being filled and passed through the machine. Fig. 2, a similar view of the same with the lower end flaps folded inwardly to rest upon the carton receiving and supporting table while being filled the lower side flaps being adapted to depend from the sides of the table. Fig. 3, a view of the same with the top end flaps folded over the contents preparatory to being passed into the carton conveyer. Fig. 4, a view of the same with the'to side flaps folded outwardly and horizonta ly as the second operation and after being pushed off of the table and engaged by one of the cross bars of the carton conveyer.

Similar numerals of reference designate like parts throughout all the figures of the drawings.

The improved machine 'fcomprises a suitable supporting frame 1, which may be mounted on suitable legs or supports 2, said supporting frame being provided with carton receiving and guiding members vertically adjustable thereon to form an intervening carton receiving and guiding or conveying guide-way 3. lThe carton receiving and guiding members are adjustable toward and from each thenso as to vary the dimensions of the carton receiving and conveying guide-way 3, to adapt the latter to cartons of varying depth or dimensions.

The carton receiving and guiding members at the front or receiving end of the machine, are in the form of upper and lower horizontally extending members 4 and 5, respectively, while those at the rear or toward the delivery end of the machine are in the form of upper and lower roller and apron carrying frames 6 and 6, respectively. The lower guide members 5, at the front of the machine are vertically adjustable through the medium of guide bolts 58, and sleeve brackets 5", the latter being adjusted on the bolts 5, by means of adjusting bolts or screws 5, and the upper member 4, is connected to a cross bar 4, mounted in the carton fiap receiving and guiding members 7, to be hereinafter described.

The upper roller and apron carrying by and are adapted to be moved simultaneously and uniformly toward and from eachother through the medium of right and left handed threaded screws or shafts 8, engaging internally threaded bearing brackets 9, the latter being mounted on the outer sides of the frames 6 and 6", and being adapted to be moved vertically toward and from each other through the guide or slotted portions 10a, of the vertically extending guide pedestals 10, on the sides of the machine fra-me, said adjusting screws or shafts 8, terminating at their top in adjusting wheels or heads 8a.

The frames 6 and 6, are provided with a series of presser rollers 1l, the rollers in the lower frame 6, being preferably mounted on stationary axle shafts 11a, while the upper presser rollers in the upper frame are mounted on vertically movable spring resisted axle shafts 11", as shown most clearly in Figs. 12 and 13 of the drawings. The ends of the vertically movable axle shaft l1", are adapted to play in vertical slots 6", in the upper frame 6, and to operate against the resistance of bow-spring members 6c, or other suitable spring resisted bearing members. If desired the presser rollers 11, may be of tubular form and mounted to revolve on the shafts 1l, and 11b, through the medium of suitable roller bearings llc.

A suitable number of presser rollers 11, are inclosed by carton receiving and sealing aprons 12, such endless aprons 12, being arranged in series said presser rollers being adapted to coperate with the carton receiving and sealing aprons 12, in .holding and sealing the carton aps as pasted and folded down by the carton flap sealing and folding mechanism to be hereinafter described. By arranging the aprons 12, in series each box or carton will be individually treated in the pressing sealing and setting operation, and it will be obvious that each box will only have to move the apron immediately in contact therewith as likewise the roller as distinguished from the case where the apron extended the entire length of the upper frame or the lower frame 'and inclosed all the rollers thereof.

Referring now to the front or carton receiving end of the improved machine, and more particularly to the carton conveyer adapted to carry the cartons from the table to the carton guide-way between the upper and lower members 4 and 5,- respectively, and the carton flap receiving and guiding members at the sides of lsaid conveyer, together with the paste applying and flap operating or folding devices, it will be seen that the machine is provided at its front with a carton receiving and supporting ing over a small sprocket 32, on the shaft table 13. The carton receiving and sup- 20, which receives its motion from the moporting table 13, is adjustable vertically tor 22, through the pulley 21, and belt 20, and laterally through the medium of a verand it will be obvious that by reason of the tical stem or support 135, carried upon a gearing above referred to that the second 70 cross bar 14, the latter being adjustably carton conveyer is given a relatively slow mounted in rearwardly extending bars 15, movement and the members uw,24", ofsuch and the parts 13, and 1.4, may be secured conveyer are provided with a series of cross in various adjusted positions through the bars 24, preferably spaced to correspond 1o medium of set screws or bolts 16. The arms appximately to the length of the cartons 75 or bars 15, extend from bearing brackets to be lconveyed between the carton receiving 17, at the rear or feed'end of the machine, and sealing aprons and presser rollers carsaid brackets 17, being provided with idle ried by the adjustably mounted frames 6 sprocket wheels 18, and similar brackets and 6 15 19, are arranged farther to the rear and are Referring now to the carton receiving or 8o provided with sprockets 20, the sprocket feeding end of the machine and the manwheels 18 and 20, being arranged in pairs ner in which such cartons are pushed and and mounted on shafts 18a, and 20a, the filled and then fed into the machine through lower shaft 20a, extending across beneath the medium of the first carton conveyer and 20 the frame and being provided with a pulley along the carton iap receiving, paste apply- 85 21, adapted to receive motion through the medium of a belt 21", communicating with a suitable source of power such as a motor 22. The sprocket wheels 18 and 20, carry '25 the endless members of the carton conveyer,

said members, in the present instance, comprising sprocket chains 23, provided with carton engaging and feeding cross bars 24. It will be seen that the upper member of 30, the carton conveyer travels within the carton receiving and conveying guide-way. 3, from front to rear and substantially midway between the upper and lower meming and flap operating or folding members or devices, Figs. 1 to 7, inclusive, illustrate successive steps or positions of the carton and its flaps from its initial position as received at the I'eedingend of the machine and 9o as pasted and fed through the same until it finally emerges from the machine in a completely pasted and sealed condition as illustrated in Fig. 7 of the drawings.

rlhe operator at the feeding end of the ma- 95 chine receives the carton 33, in substantlally the position shown in Fig. l of the drawings and then folds the lower end flaps bers- 4 and 5, respectively. As a means of 34, inwardly as shown in Fig. 2 of the drawmoving the sprocket chains 23, toward and ings and rests the carton in such position 10o from each other for adjusting to cartons upon the carton receiving and supporting of varying width the cross bars 24, are preftable 13,while being filled, the lower side flaps erably in the form of tubular members 35,'being adapted to depend from the sides mounted upon stub pins or shafts 23, eX- of the table and after being filled on such lo tending from some of the links of the chains table the operator then folds the top end 10 and arranged at suitable intervals, and as flaps 36, over the contents of the box and in a means of moving the sprocket wheels 18 such position pushes the same forwardly to and 20, correspondingly the bearing brackrest upon the adjacent receiving end of the ets 17 and 19, are transversely vmovable or low'er guide member 5, and between the adjustable in transversely-extendinggrooves members 23, ofthe rst carton conveyer, 110 17a, and 19a, in a well known and underafter which the operator turns the top side stood manner. The sprocket wheels 20, cn flaps 37, outwardly and horizontally to the the lower shaft 20, are adapted to be moved position indicated in Fig. 4 of the drawings, to meetthe varying adjustments above resaid top side flaps taking over the flap referred to. ceiving and guiding members 7, after which 115 The second carton conveyor at the rear of the lower side flaps 35, are moved to the the machine is a more slowly moving one horizontal position shown in Fig. 5 and are and is similarly constructed and mounted, brought into engagement with the flap resaid jconveyer comprising endless sprocket ceiving and guiding members 38, at the chains 24", mounted on sprocket wheels 25, sides of the lower carton guide or support 5, 120 said wheels 25, being mounted on vertically such guiding members 38, serving to prevent extending brackets or pedestals 26, the the lower side flaps from falling downupper rear pair of sprocket wheels 25, bew'ardly, and as a means of holding said ing mounted on a driving shaft 25a, proside flaps 35 and 37, in a substantially hori- 60 vided with a gear wheel 27, meshing with Zontal position while receiving the paste or 125 a pinion 28, said pinion being carried on the adhesive material from the paste applying end of a second shaft 29, and the latter bemembers 39, leading from the paste resering provided at its opposite end with a voirs or receptacles 40, said reservoirs or resprocket wheel 30, the latter receiving its ceptacles 40, are provided with supplemotion from a sprocket chain 31, extendmentary Hap guide members 40a, and it will 13 bolts 419, and it will also be observedI that such reservoirs 40, and guide members'40,

are adjustable toward and from each other`f` or transversely of the machine through the medium of transverse guide slots 42, and

clamp base plates 42a, in an obvious and well known manner and for the purpose hereinbefore referred to' in connection with the bearing brackets 17, and 19, in the slots 17, and 19a. It will also be observed that the upper carton guide member- 4, is provided at its front with a pivoted supplementary guide 4b, to hold down the top end flaps 36,

during the initial insertion of the carton and while the side fiaps 37, and 35, are being positioned as hereinbefore referred to.

As a means of returning the pasted side flaps 35, and 37, over the contents of the carton and as received from the paste applylng members 39, four curved carton Hap operating or folding members 43, are provided,

said members 'being preferably arranged in pairs at the sides of the guide members 4, and 5, the receiving ends 43, thereof belng arranged below and above the horizontal planes of the members 4, and 5, so as to engage the forward ends of the horizontally extending side flaps, the unsealed sldes thereof riding over the curved flap operating or folding members 43, in an obvlous manner whereby said sealed flaps are returned to a horizontal position above and below the carton contents the carton emerglng from the horizontally extending delivery portions 43h, of the flap operating or folding members and the cross bar 24,. of the carton conveyer positioning the closed or sealed box in a true and proper position into the receiving ends of the first set of carton receiving and sealing aprons 12, where it is engaged by one of the cross bars 24, of the second conveyer and this second conveyer moving in a slow manner will slowly move the closed cartons through between the various aprons l2, and presser rollers 11, any slight variations in the thickness of the cartons or the surfaces of the upper flaps caused by unevenness in the carton contents being taken up or relieved by the springs 6, operating against the axle shafts 11b, carrying the upper presser rollers 11, and it will be apparent that when the carton finally emerges from the delivery end of the machine after being subjected to the action of the sealing aprons 12, and presser rollers 1,1, the paste will be thoroughly set or dried so that the flaps will be securely sealed for transportation or storage. It will also be observed that the flap operating or folding members 43, are vertically adjustable on supporting stems or bars 44, through the medium of brackets 45, and set screws or bolts 45, and that the stems or bars 44, are adjustable toward and from each other through the medium of transverse guide slots 46, and clamp base plates 46, for the purposes of adjustment as hereinbefore descrlbed.
